I've been breaking-in my Moki 1.8 these last couple days and I can tell you its an awsome! awsome engine! It loves to start wet, but after that, one flip or two everytime and it starts right up. I was taching with a Menz 18 x 8 wood prop @ 6,500 for my very very first tank through it running 5 turns out using FAI NO NITRO in it.
